Studenteropgave: Basisprojekt

Abstrakt

Hazardous substances are present in many plastic materials, which are used to produce a wide range of products. Wear and tear of these products result in an indirect release of microplastic particles, and the toxic substances from these particles, into the nature.
In this project we wish to examine how microplastic particles, from the usage of tires, travel through our nature and what effects these particles, and the hazardous substances they carry with them, have on us and our environment. We wish to understand how hazardous substances are carried with microplastic particles, and what the extent of their dispersal is.
This paper firstly explains why a dispersal of microplastic particles from tires happens, and how hazardous substances also are dispersed this way. Thereafter, it outlines the dispersal of microplastic particles via rainwater, in different scenarios with high microplastic concentration from tires. After tracking the microplastic dispersal route, this paper presents a redesign of an existing city-based rainwater management system which includes a procedure of collecting microplastic particles. The goal of our new alternative system is to lower the dispersal of microplastic particles from tires, and thereby also reduce the negative effects of the hazardous substances present within these particles.
While working on this paper, we discovered that a technology lock-in exists in the way rainwater is handled. If a technology shift currently is taking place, this opens up an opportunity to examine whether the implementation of a tubular membrane module system into the new rainwater management system, could potentially eliminate a fraction of the dispersal of microplastics from tires.
